Concrete Scanning in BC
Before anyone cuts, cores, drills or anchors into structural concrete, you need to know what's inside. Ground-penetrating radar images the slab or wall — rebar, post-tension cables, conduit and voids — non-destructively, so the work is safe. For owners, engineers and contractors across British Columbia.
Leaks.ca is the educational leak detection hub and service-support division of Leak.ca, helping BC property owners understand leak risks and connect with professional detection services when needed.
Radiation-free & single-sided. GPR scans concrete from one side in real time with no ionizing radiation — so work continues around it. See GPR vs. X-ray →
Imaging
Image the inside of a slab or wall — reinforcement, embeds and voids — from one side, in real time.
Scan parkade and post-tensioned suspended slabs — the highest-risk concrete in any building.
Image inside concrete walls and floor slabs before drilling, cutting or anchoring.
Image structural concrete and the ground beneath it to inform engineering and excavation.
Reinforcement
Map the reinforcement grid and cover so penetrations and anchors land safely between bars.
Locate tensioned cables precisely — striking one is a serious safety and structural event.
Find the electrical conduit, pipe and embeds in a slab before a core severs a live service.
Pre-Penetration
Condition
For Pros & Contractors
Every core and saw-cut into structural concrete risks a post-tension cable or conduit. A pre-cut GPR scan clears the path so the blade never finds a surprise.
Assessment and design depend on knowing what's in the concrete. Engineers use GPR scanning to map reinforcement, measure thickness and find defects non-destructively.
On a live site, a struck cable or severed conduit stops the job. GCs scan concrete before penetrations to keep trades moving and the structure protected.
Anchors and fasteners must land in clear concrete. Scanning before drilling protects the fixing, the rebar and any embedded conduit.
Parkade and structural restoration means cutting out and replacing concrete around tendons and rebar. Scanning makes that work safe and targeted.

Concrete Scanning FAQ
Concrete scanning uses ground-penetrating radar (GPR) to image the inside of a slab or wall — rebar, post-tension cables, conduit, embeds and voids — non-destructively, from one accessible side. It's the safe, radiation-free standard before cutting, coring, drilling or anchoring into structural concrete.
Structural concrete hides rebar, post-tension cables and conduit. Striking a post-tension cable is dangerous and can compromise the structure; cutting a conduit causes outages. GPR scanning maps these so penetrations are placed safely — the standard of care before any cut, core or anchor.
For most work, yes. GPR needs access to only one side, gives real-time results, and uses no ionizing radiation, so surrounding work continues and no area is cleared. X-ray is reserved for rare cases needing maximum detail with two-sided access. See our GPR vs. X-ray comparison.
